GM-416-8B MLTL Corner Cabinet

[srivenkat]

Hi Sri,
1) Yes GM's original 45 degree design offers the least intrusion into the room as it is rotated (I think).

2) I have worked for a short time in a cabinet shop, so I am biased towards the most complex shape possible. However, if this is your first build, a rectangle will be simplest and the 45 degree next.

3) A plain rectangle will work fine, but in my experience with a similar width room, spaced as wide as I can get them is best for me. I will draw it up and post it so you can see.

Here are my 28"x42" rectangular speakers in my room, I actually have to pull them out into my room so that they line up in an arc with my center channel:

Thanks VolvoHeretic. Looking at all various versions, though it is my first build and might be bit of a challenge I can go with GM's 45 degree. I am ready to roll! Next step is to understand the inside bracing, I will look forward to inputs/advice.

Thanks a lot.

Option 1 - Curved Cabinet ? Tough one! I won?t be able to build this myself.

Greets!


Gotten kind of behind and still short of time, so just a ~ quick note........ don't start 'burning' wood yet except to do the baffle since I've more to post WRT the whole curved/tapered/bracing subject and don't forget that the 811 ideally needs to be set back in a recess along with its foam inserts same as the M19's to use its XO, which I didn't see shown.


Trust me, anybody with the ability to use a few basic hand tools can do a curved [ML]TL.


Anyway, thanks all for the great tutorial help, input, for this project and especially for future reference!

Does anyone have a 811 exposed that they could measure for me? I know the flange width and height and also the overall length, but I need to know the height of the horn mouth and its width in front of the flange. I have a 511 and tried to scale it down, but I don't trust the dimensions.

Wonder why it's so far off from the drawing that me and no doubt hundreds around the world used way back when and were a 'drop-in' fit.

Greg, what curved design do you have in mind. Might be worth doing a drawing and saving here, for posterity and all that....

In the fullness of time and more importantly, VolvoHeretic's continuing assistance........... today, it's replace a worn out, beat to crap mailbox/post and rearrange the yard's mid-calf deep, mass blanketing of leaves/dead limbs. Our drought and increasing winds combined with record low humidity has us in a fire RED alert, so with five large/tall trees overhanging the house and increasing breeze up here on the the hill........
